Problems solved by technology

[0004] However, for example, in the exhaust pipe (chimney) of a ship, etc., it is not always possible to ensure a suitable working environment. Therefore, for example, when replacing a sensor, it is necessary to attach and detach screws that are small parts and many screws that are small parts. When homework becomes extremely complicated and difficult
Specifically, it is easy to cause the screw to fall off or the screw head to be damaged
[0005] In addition, since there are cases where, for example, the exhaust gas of the relevant ship is rich in soot and is at a high temperature above 500°C, there are also cases where soot is stained on the screw head or the screw is burnt to the sleeve, so the operation in this case Difficulty will increase further

Embodiment Construction

[0029] Hereinafter, an embodiment of an exhaust gas analyzer according to the present invention will be described with reference to the drawings.

[0030] The exhaust gas analysis device 100 according to the present embodiment is installed, for example, in an exhaust pipe of a marine engine and is used to analyze a specific component (for example, NO) contained in the exhaust gas flowing therein. x , SO x , C0 2 , CO, etc.) direct plug-in device.

[0031] Specifically, as figure 1 As shown, the device has: a detection unit 1 having a sensor main body 32 for detecting the specific component inside; an analysis unit ( not shown); a flange-shaped mounting portion 6 for fixing to the exhaust pipe. In a state where the exhaust gas analysis device 100 is attached to the exhaust pipe, it is configured such that the front end portion of the detection unit 1 protrudes into the exhaust pipe.

[0032] Since this embodiment is characterized by the detection unit 1 , the detection uni...

Abstract

The invention provides an exhaust gas analyzer which can ensure satisfactory operation when a gas sensor is replaced during the first-stage assembling, the assembling and the maintenance and a probe unit. The exhaust gas analyzer includes a gas sensor for detecting the specified content in waste gas and a sleeve. The sleeve is provided with a main body for inserting the gas sensor inside an inserting hole and a cap component threadedly connected with the main body and being configured to covering the insert hole. Meanwhile, the gas sensor is clamped by the cap component and the main body to be fixed in the sleeve by means of threadedly connecting the cap component to the main body.

Description

technical field [0001] The present invention relates to a method for analyzing the oxygen and nitrogen contained in the exhaust gas flowing through the exhaust pipe installed in the exhaust pipe of combustion equipment related to internal combustion engines and boilers for ships, waste combustion furnaces, industrial furnaces, etc. An exhaust gas analyzer for specific components such as oxides and a detection unit for the exhaust gas analyzer. Background technique [0002] As such an exhaust gas analysis device, there is known a device that detects a specific component in the exhaust gas while sampling the exhaust gas with a detection unit that is directly inserted into the exhaust pipe and installed as disclosed in Patent Document 1. [0003] Specifically, the detection unit has a cylindrical sleeve and a gas sensor housed in the sleeve to detect a specific component of the exhaust gas. Furthermore, the conventional gas sensor is screwed and fixed at many places on the fro...
